. IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 152,852, dated July 7, 1874; application filed May 27, 1874.

To all whom it may concern:

Be it known that I, GEORGE R. LYON, of

Chicago, in the county of Cook and State of provement in lamp-burners,by means of which the wick can be more readily manipulated and a steadier and more uniform light obtained; and my invention therein consists in the novel construction and arrangement of the principal operative parts, as is more fully hereinafter explained.

In order to enable others skilled in the art to make and use my invention, I proceed to describe the same in connection with the drawing, in which- Figure lis a vertical central section through the longest diameter ofthe tube. Fig. 2 is a view of the same looking from the other side. Fig. 3 is a vertical central section at right angles to that in Fig. l, and Fig. 4 is a perspective view of the tube.

The frame A of the burner is of the ordinary construction, split and slotted vertically at regular intervals, in order to receive and hold the base of any chimney which may be placed within it. rIhis cap or holder, or frame A, terminates in a short cylinder, a, of somewhat less diameter than the bottom of A, and on the outside of which a thread is cut for the purpose of screwing' the burner into a lamp. A tube, B, of such a shape as to take an ordinary hat wick, is secured into the base ofthe cap or holder a, which is closed, except where the tube passes through it, said tube projecting a short distance below the base a. The tube B is enlarged on one side at its base at b, said enlargement extending from the base. to about one-third the height of the tube B. In this enlargement b, which is rectangular, a iiat rectangularshaped spring, O, is fitted, said spring being soldered or riveted to the base, and bent into the tube so as to fit into the enlargement b. When. pressed upon, the spring will recede into the enlargement, and thus allow the wick to pass. This spring may be made of any metal, and can be readily replaced. On the opposite side of the tube B three vertical slots, D, are cut to allow the entrance of the teeth of the ratchet-wheels el, placed on the rod E, provided with a small wheel, c, to turn it. The rod E passes through the sides of the cap or holder A, outside of the tube I3, and the ratchet-wheel d, secured to it at equal distances apart, revolving in the slots D, which are out symmetrically in the tube B, to so take hold of the wick that all parts of it are compelled to rise at the same time. The enlargement b is provided with holes above and below the base a. Those in that portion of the tube B which extend below the base a allow for the escape ofthe gas which may be formed in the lamp, and those above the base a allow the external air to enter to the wick. The gas and air pass behind the spring in each instance, and the motion caused by the revolution of the ratchet-wheels allows said gas and air to circulate freely. By this means the wick is kept soft, free from gummy collection, and cool, and the flame is constant and regular. Now, if a wick be introduced into the tube B it may be controlled by means of the ratchet-wheels d and the spring C, which presses the wick against the wheels with a uniform pressure, the equal distribution of the wheels and the pressure of the spring insuring a regular and unembarrassed motion.

Having thus described my invention, what I .claim as new isl In a lamp-burner, the combination of a wicktube enlarged at its base and pierced to admit air from the exterior, and to allow gases to escape from the interior of the lamp, a spring which recedes into said enlargement, and a series of ratchet-wheels whose spindle is outside the tube, and which operate through vertical slots in the tube directly opposite to the spring before mentioned, the several parts being constructed and arranged substantially as described and shown.

This specification signed and witnessed this 6th day of May, 1874.

GEORGE R. LYON.
